局部

Objective To assess the effectiveness and safety of local versus systemic application of opioids for labor analgesia.

目的 运用Cochrane系统评价的方法，评价分娩时局部和全身应用阿片类药物镇痛的有效性与安全性。

Weierstrass took the concept of "analytic Gebilde" as basic constitution to analytic continuation in order to access to integer analytic function by local ones.

魏尔斯特拉斯以"解析映射"概念为基本构成，进行解析延拓，从而实现由局部获得整体解析函数。

The content of this course is: analytic function (the definition of analytic function, elementary functions, etc.), conformal mapping (the definition if conformal mapping, fractional linear functions, elementary mappings, etc.), complex integration (Cauchy's integral formula, Cauchy's theorem, etc.), Series (Laurent Series, singularities, local property, etc.), residues and its applications (the Residues Theorem, integration by residues, the Argument Principle, the Maximum Principle, Schwarz's Lemma, etc.), analytic continuation and harmonic functions, etc.

本课程内容主要包括：解析函数(解析函数的定义、初等函数等)、共形映射(共形映射的定义、分式线性变换及初等映射等)、复积分(Cauchy 积分公式、 Cauchy 定理等)、级数(Laurent 级数、孤立奇点、局部映射等)、留数及其应用(留数定理、利用留数计算积分、幅角原理、最大模原理、 Schwarz 引理等)、解析开拓和调和函数等内容。

Fully and clearly analytic expression of multiwavelet transformation is given .The experiment of speckle reduction to US image is implemented by choosing local error as threshold. Results show that multiwavelet transformation is useful for speckle reduction and there have little noise and reserve important image features such as boundary when compared to results obtained from existing the denoising methods alone.

在二维图像阵列的应用方面，通过采用局部方差作为阈值，对超声斑纹图像进行阈值化去噪处理的实验结果表明，多小波变换在有效抑制斑纹噪声的同时，相对于其他方法还能更好地保留原图像的边界等重要特征信息。

Abstract］ objective to study the pathological features and histopathological type and differential diagnosis of hepatic focal nodular hyperplasia.methods the clinicopathological characteristics of 40 cases of fnh were studied.all were evaluted by use of paraffin embedded sections and he staining before light microcope observation.results there were 28 females and 12 males fnh patients whose age were from 16 to 62 years（median 41.3）,all alpha-fetoprotein was negative and had no hepatitis history.25 cases were classic type showed characteristic central stellate fibrotic scar,composed of fibrous connestive tissue and tortuous blood vessels.8 cases were telangiectic type,the left were mixed type and adenomatoid type.conclusion fnh is a reactive proliferation of hepatic cells to local blood vessel anomalies,it is not realy a tumor.its differential diagnosis includes hepatic adenomatous hyperplasia nodule,hepatic anaplasia nodular hyperplasia,fibrolamellar hepatocellular carcinoma and hepatocellular adenoma.

目的 探讨肝局灶性结节性增生的病理形态特点、组织分型及鉴别诊断。方法分析40例肝局灶性结节性增生的临床资料，并采用石蜡包埋he染色光镜下观察其组织学特点。结果 40例肝局灶性结节性增生患者中，女28例，男12例，年龄18~62岁，平均年龄41.3岁，所有病例术前均无肝炎病史，甲胎蛋白阴性，组织学上25例为经典型，有特征性的中央纤维瘢痕，由纤维结缔组织及扭曲血管组成。8例为毛细血管扩张型，其余为混合型及腺瘤样增生型。结论肝结节性增生是一种肝细胞对局部血管的异常反应性增生，并非真性肿瘤，主要与肝腺瘤样增生性结节、肝间变性结节状增生、肝纤维板层癌及肝细胞腺瘤鉴别。

And if you think about it, all these different societies have different geometric design themes they use. So Native Americans use a combination of circular symmetry and fourfold symmetry. You can see on the pottery and the baskets ... Here's an aerial photograph of one of the Anasazi ruins; you can see it's circular at the largest scale, but it's rectangular at the smaller scale, right?

事实上，不同的社会有不同的几何建筑规划方案，在北美，人们喜欢圆形对称、四重对称，你可以在陶罐和篮子上看出来……这是Anasazi遗迹的航拍图，图上看出大局上呈现圆形，而局部则呈现方形。

Pretreatment can take full advantage of the local rock layers or the stability of their own, linked with the excavation layered reinforced concrete spraying.soil and debris to avoid the small joints broken rock slope collapses, and earth pressure anchor plate passed by the concentrated suspension bolt,bolt through the anchoring force of earth pressure balance.

可以充分利用岩土层自身或预处理的局部的稳定性，随基坑开挖分层挂钢筋网喷射砼，以避免土层碎片及岩石边坡小的节理破碎坍塌，并把土压力传给锚板，由锚杆集中受力，通过锚杆的锚固力平衡土压力。

Local anesthesia is necessary in less then 40% of the cases.

要在局部麻醉的情况下不到40%。

You can also benefit from a local anesthesia if you are a highly sensitive patient.

你也可以从一个局部麻醉，如果你是一个高度敏感的病人。

We'll give you local anesthetic .you are a brave fellow.

不会疼的，我会给你做局部麻醉，你是个勇敢的人。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
